Jonah that link doesn't work for us, (at least not for me).
I get an https Google Accounts Service Login page Login Page.
The full url is huge!
I've broken it down below for all to see.
I just tested that link "Login Page" above, and only get a Page not found now. Weird.
when i try to load the mail.google.com/mail URL using IE6, i get a longggggggg pause with various 'loading' indicators and finally a white screen with the following URL
everything is OK with FF3, any ideads?
